I application filed April 22 Serial No. 163,670.

improvements in cooling devices and par ticularly to devices for cooling milk.

One object of the-present invention is to provide novel and improved device whereby the milk, drawn from the cow, can be immediately cooled, in a can or in a bucket, before being poured into-the can.

Another object is to provide a novel and improved structure of this character which is adapted for ready application to or removal "from the milk buckets or cans thus rendering it easy to use the device in one bucket or can and then remove it and use it in another bucketor can. i

A further object is to provide a novel and improved device of this character which, when applied to the bucket or can filled with milk. will permit cold water to pass thercthrough to cool the milk.

A still further object is to provide a novel and improved device of this character which is capable of being applied to the bucket or can and rocked back and forth, within the.

milk, while at the same time cold water is contained in the device or is flowing therethrough.

Other objects and advantages will be ap parent from the following description when taken in connection with the accompai'lyin r drawing.

In the drawing:

Figure 1 is a side elevation of a milk bucket showing the invention attached there in. v

Figure 2 is a top plan view of the bucket slightly reduced showing the position of the device.

Figure 3 is a vertical transversesectional 1 view through the bucket, taken on the line 3-3 of Figure 2, showing the invention in side elevation.

Referrin oarticularl to the accomnan 2:: i r i ing dr wing, 10 represents a milk bucket which has the diametrically opposite openings 11 and 12, near the upper end thereof, the purpose of which will presently appear.

Thecooling device comprises a substantially U-shaped pipe 13 which is disposed within the bucket with its ends uppermost.

The'smaller end 14f is turned outwardly and downwardly to extend over the upper edge of the bucket, as shown at 15, while the other end extends vertically upward above the bucket and atthe other side, in the form of a funnel 16. On the outer face of the funnel thereis mounted a handle 17 Secured tothe leg ofthepipe '18. below'the funnel, and

within the bucket, is an upwardly and out- 'wardly inclined resilient. arm 18. the upper end of which is turned outwardly, as at 19 and is disposed through the opening 11 of the bucket. Secured to the other leg of the pipe 13, and also within the bucket. is an upwardly and outwardly inclined resilient arm 20, the intermediate portion of which is bent to form an outwardly extending lug 21 disposed in the other opening 12 of the upper end of the bucket. The portion of the arm 20, above the lug, extends above the portion 15 of the first leg, and above the upper edge of the bucket, to provide a handle 22 which is to be grasped to flex the arm inwardly and disengage its lug 21 from the opening 12, when the device is to be removed from the bucket. v

It will be noted that the end 19 and the lug 21 are disposed in the same plane, and when engaged in the openings 11 and 12,

of the bucket, serve as trunnions for thepipe '13, and when the handle 17 is grasped the pipe can be rocked or swung within the bucket, with the'result that, the portion of said pipe which is within the milk will be moved back and forth through the milk and cause the rapid cooling of the same. To aid the cooling of the milk, water of a low temperature is poured into the pipe 13, through the funnel. This may be arranged so that a continuous flow of cold water is maintained through the pipe, thus producing the proper reduction of temperature in a shorter time than when a certain quantity of water is placed in the pipe and the same rocked back and ,forth.

By-means of the flexing of the arm 20, the device is readily removable from one bucket and applied .to another, with the result that a single person can quickly cool a large quantity of milk, within a short space of time, and without any great amount oflabor.

a much longer time than otherwise.

from multiplying as rapidly as they would were the milk retained any length of time before being cooled.

The fact that the device can be easily and quickly applied to and removed from the milk bucket, renders the device one which can be handled with facility and economy, thus doing away with the usual expensive cooling systems generally required.

While I have shown the device usedin connection with a milk bucket, I wish it understood that other receptacles may be used with the same results, as for instance the large five or ten gallon milk cans. In the latter case larger quantities of milk can be cooled at one time.

What is claimed is:

1. In a milk cooling device, the combination with a receptacle having diametrically opposite openings in the upper end, of a Ll-shaped conduit disposed in the receptacle for rocking movement, and resilient means on the legs of the conduit for detachably engaging in said openings and supporting the conduit in position for such rocking movement.

2. In a milk cooling device the combination with a receptacle having openings adjacent the upper end, a Ushaped pipe disposed vertically in the receptacle, said pipe being arranged to receive a cooling medium therethrough, a handle carried by the upper end of one of the le s of the pipe, a flexible arm secured to said leg and having a lug journaled in one-of said openings, and a second resilient arm carried by the other leg of the pipe and formed with a lug journaled in the other opening whereby the pipe is capable of rocking movement in the liquid in the receptacle, and ready removal from the receptacle upon flexing the last-named arm to release the lug from the opening.

In testimony whereof, I allix my signature, in the presence of two witnesses.
